We have used the VLA in A configuration to obtain spatially resolved 2
1 cm absorption spectra of NGC 1068 and NGC 3079. The bulk of the abso
rbing H I in NGC 1068 appears to be located in the inner disk and is o
riented such that the brighter, northeast radio lobe is located in fro
nt of the disk and the fainter, southwest radio lobe is located behind
. We find evidence for a shock front inside the leading edge of the st
ellar bar based on the kinematics and column density distribution of t
he H I. Near the radio nucleus of NGC 1068 the H i appears to be parti
cipating in a wind-driven outflow. In NGC 3079 we detect slightly reso
lved H I absorption against the radio core. This absorption is charact
erized by strong, multiple components: (1) broad absorption (FWZI grea
ter than or similar to 895 km s-1) with a deep core near the systemic
velocity and a slight blue asymmetry, and (2) red- and blueshifted com
ponents which are slightly resolved by the VLA beam. These Doppler-shi
fted components might arise in a wind-driven outflow or a slightly res
olved circumnuclear ring (approximately 90 pc radius). Assuming circul
ar orbits, the virial mass interior to the alleged ring would exceed 1
0(8) M..
